Located just a 35-minute drive from downtown Boston, Wompatuck State Park offers 262 wooded campsites (140 of them with electricity), 12 miles of paved bicycle trails, and many miles of wooded bridle paths and hiking trails. The park is very popular with trailer campers: electrical and water hookups are available. Fishing is allowed in the Cohasset Reservoir. A boat ramp is provided for car-top boats, but no boat trailers, please.

One of the most notable features of the Park is Mt. Blue Spring which is a popular source of fresh drinking water. Visitors can help themselves for free. The park is named for an Indian chief the local colonists knew as Josiah Wompatuck. In 1665, Chief Wompatuck deeded the park and the surrounding land to the English settlers. During WWII the park was used as an ammunition depot by the US military.
